This paper investigates the application of the Generalized Likelihood Ratio Test detector to the Global Navigation Satellite System array-based acquisition problem. We consider an unstructured channel model which includes colored noise with an arbitrary covariance matrix. We show that the proposed test function is a Constant False Alarm Rate detector and we provide closed form expressions for false...
In this paper, we present a new scheme for uplink SIMO CDMA/TDD transmission using Pre-RAKE diversity combining and new orthogonal spreading sequences at terminal, and simple space-time array receiver at base station. Adopting techniques such as so-called zero correlation duration (ZCD) code as spreading code, chip-level beamformer (CLB) array antenna configuration, and one single matched filter for...
Multi-users system technology, array processing and space-time beamforming are recent methods invented for wireless communication schemes. An arrayed vector-input, vector-output (VIVO)DS-CDMA system is treated in this paper. We treat in particular the capacity of multi-users detectors using beamforming technology. At this stage, a new mathematical formulation in terms of capacity for various space-time...
Due to the disability of MSINR beamforming receiver to correct for the carrier frequency offset in MC-CDMA uplink systems, we present a new combined MSINR beamforming and MMA algorithm. While MSINR beamforming provides an appropriate beam pattern having its maximum gain along the desired user direction, the suggested MSINR-GCMMARY can capture the desired signal and compensates for carrier frequency...
